1. Which artery is most commonly used for routine arterial injection during
embalming?
A. Radial artery
B. Femoral artery
C. Common carotid artery
D. Popliteal artery
Answer: C. Common carotid artery
The common carotid artery provides excellent distribution of embalming solution
to the head and body and is one of the most frequently selected injection sites.
2. The primary purpose of embalming is to:
,A. Permanently preserve human remains
B. Restore life functions
C. Temporarily preserve, disinfect, and prepare the body for viewing
D. Eliminate all microorganisms
Answer: C. Temporarily preserve, disinfect, and prepare the body for viewing
Modern embalming delays decomposition, reduces health risks, and enhances
presentation but does not permanently preserve remains.
3. Rigor mortis is caused primarily by:
A. Blood clotting
B. Bacterial activity
C. Chemical changes in muscle tissue after death
D. Air entering the muscles
Answer: C. Chemical changes in muscle tissue after death
ATP depletion causes muscle fibers to remain contracted, resulting in stiffness.
4. Livor mortis refers to:
A. Cooling of the body
B. Drying of the skin
C. Discoloration caused by settling of blood after death
D. Muscle stiffening
Answer: C. Discoloration caused by settling of blood after death
Gravity causes blood to settle in dependent areas, creating purplish discoloration.
5. Algor mortis is:
A. Dehydration after death
,B. The gradual cooling of the body after death
C. Blood clot formation
D. Skin discoloration
Answer: B. The gradual cooling of the body after death
The body gradually approaches the surrounding environmental temperature.
6. Which cavity organ is usually aspirated first?

8. The recommended concentration of arterial fluid depends primarily on:
A. Body height
B. Hair color
, C. Condition of the body and degree of preservation needed
D. Eye color
Answer: C. Condition of the body and degree of preservation needed
Body condition, decomposition, edema, and time before disposition influence
fluid strength.
9. Which chemical is the primary preservative in most arterial embalming
fluids?
A. Ethanol
B. Methanol
C. Formaldehyde
D. Acetone
Answer: C. Formaldehyde
Formaldehyde cross-links proteins, slowing decomposition.
10.Formaldehyde preservation occurs primarily by:
A. Freezing tissues
B. Drying tissues
C. Cross-linking tissue proteins
D. Increasing moisture
Answer: C. Cross-linking tissue proteins
Protein fixation creates resistance to bacterial and enzymatic breakdown.
11.Edema is defined as:
A. Blood clotting
B. Gas formation
C. Excess fluid accumulation in body tissues
